Class Random

Provides random functions. this is a high-level wrapper for UnityEngine.Random.

Properties​

normalDistribution​

Built-in normal distribution randomizer.

public static Randomizer normalDistribution { get; }

Methods​

SetSeed(int randomSeed)​

Set a random seed.

public static void SetSeed(int randomSeed)

SetState(State randomState)​

Set a random seed (Represented by UnityEngine.Random.state).

public static void SetState(State randomState)

GetState()​

Get current random seed (Represented by UnityEngine.Random.state).

public static State GetState()

Bool()​

Returns a random System.Boolean value.

public static bool Bool()

Range(int baseValue, int interval)​

Returns a random int value in the range [baseValue-interval, baseValue+interval].

public static int Range(int baseValue, int interval)

Int(int max)​

Returns a random int value in the range [0, max).

public static int Int(int max)

Int(int min, int max)​

Returns a random int value in the range [min, max).

public static int Int(int min, int max)

Int(Vector2Int range)​

Returns a random int value in the range [range.x, range.y].

public static int Int(Vector2Int range)

GetValueByProbability(int min, int max, float probability)​

Returns a value within the inclusive range [min, max] based on a probability.

If probability is 1, returns max;

If probability is 0, returns min;

If probability is between 0 and 1, uses a "roulette-wheel" style of incrementing from min toward max based on that probability.

public static int GetValueByProbability(int min, int max, float probability)

Pick(int min, int max, int count)​

Returns count random numbers from the interval [min, max].

public static IEnumerable<int> Pick(int min, int max, int count)

Pick<T>(T object1, T object2)​

Randomly select one from object1 and object2.

public static T Pick<T>(T object1, T object2)

Shuffle<T>(IList<T> list)​

Shuffle the elements of a list. This method ensures that each element is no longer in its original position.

public static void Shuffle<T>(IList<T> list)

Vector3(float min, float max)​

Returns a random UnityEngine.Vector3.

public static Vector3 Vector3(float min, float max)

Vector3(Vector3 min, Vector3 max)​

Returns a random UnityEngine.Vector3.

public static Vector3 Vector3(Vector3 min, Vector3 max)

Vector2(float min, float max)​

Returns a random UnityEngine.Vector2.

public static Vector2 Vector2(float min, float max)

Direction()​

Returns a random 3D direction.

public static Vector3 Direction()

Direction(Vector3 startDirection, float maxAngle, Vector3 axis)​

public static Vector3 Direction(Vector3 startDirection, float maxAngle, Vector3 axis)

Direction(Vector3 startDirection, Vector3 endDirection, [bool safe = true])​

Returns a random 3D direction between startDirection and endDirection.

public static Vector3 Direction(Vector3 startDirection, Vector3 endDirection, [bool safe = true])

Direction2D()​

Returns a random 2D direction.

public static Vector2 Direction2D()

Direction2D(Vector2 direction, float maxAngle, [bool safe = true])​

Returns a random 2D direction by rotating direction by a random angle within the range [-maxAngle, +maxAngle].

public static Vector2 Direction2D(Vector2 direction, float maxAngle, [bool safe = true])

Direction2D(Vector2 startDirection, Vector2 endDirection, [bool safe = true])​

Returns a random 2D direction between startDirection and endDirection.

public static Vector2 Direction2D(Vector2 startDirection, Vector2 endDirection, [bool safe = true])

Range(float baseValue, float interval)​

Returns a random float value in the range [baseValue-interval, baseValue+interval].

public static float Range(float baseValue, float interval)

Float01()​

Returns a random float value in the range [0, 1].

public static float Float01()

Float(float max)​

Returns a random float value in the range [0, max].

public static float Float(float max)

Float(float min, float max)​

Returns a random float value in the range [min, max].

Float(Vector2 range)​

Returns a random float value in the range [range.x, range.y].

public static float Float(Vector2 range)

FloatNormalized()​

Returns a random float value in the range [-1, 1].

public static float FloatNormalized()

PerlinNoise(float x)​

Returns the Perlin noise in the range [0, 1] based on the sample point x.

public static float PerlinNoise(float x)

PerlinNoiseNormalized(float x)​

Returns the Perlin noise in the range [-1, 1] based on the sample point x.
